Be it fiction, philosophy, history or any other genre of book you might consider to be of Eastern origin or influence. What would you consider to be essential, or at least a very good read?

I'm moving to South Korea for a year in a few weeks, and would quite like to take the opportunity to divulge into all things "Eastern", particularly philosophy and maybe a few classic fiction pieces.

So far I'm only set on getting some writings on Confucius.

(Note: I recognise the humongous breadth/oversimplification of the name 'Eastern' as a genre - it's more as a guideline as I'm quite open to suggestions and don't want to be Korean specific).

Do feel free to talk about books generally.
